Abstract

Indonesia telah lama mengandalkan gas bumi sebagai sumber utama energi dalam berbagai sektor seperti transportasi, industri pupuk dan petrokimia, serta pembangkit listrik. Hal ini dikarenakan sektor gas bumi di Indonesia memiliki potensi yang menjanjikan dengan cadangan terbukti sekitar 41,62 TCF. Banyaknya kebutuhan yang bergantung pada konsumsi gas bumi di berbagai sektor ini mendorong SKK Migas untuk terus berupaya meningkatkan produksi migas dengan memperkuat infrastruktur gas bumi (Akasah, 2022). Salah satu langkah untuk meningkatkan efektivitas dari suatu equipment adalah melakukan evaluasi rutin kinerja fasilitas produksi. Salah satu metode yang umum digunakan dalam meninjau efektivitas sebuah mesin yakni menggunakan metode Overall Equipment Effectiveness (OEE), di mana didapatkan nilai rata-rata OEE unit ST Blok 1.0 selama lima tahun sebesar 81.30% di mana nilai tersebut belum mencapai standar. Perhitungan Six Big Losses menemukan faktor atau aspek yang signifikan memengaruhi tingkat efektivitas unit ST Blok 1.0 adalah reduced speed losses dengan persentase sebesar 98.38%. Kemudian diidentifikasi mode kegagalan tertinggi pada equipment HRSG dengan metode FMEA dan dilanjutkan dengan menentukan tindakan yang tepat untuk mitigasi potensi-potensi mode kegagalan yang dapat terjadi pada unit ST Blok 1.0 menggunakan metode Reliability Centered Maintenance.

Indonesia has long relied on natural gas as the main energy source in various sectors such as transportation, the fertilizer and petrochemical industry, and electricity generation. This is because the natural gas sector in Indonesia has promising potential with proven reserves of around 41.62 TCF. The large demand of natural gas in various sectors encourages SKK Migas to continue increasing oil and gas production by strengthening natural gas infrastructure (Akasah, 2022). One of the things that can be done to increase equipment effectiveness is to carry out regular evaluation of the effectiveness of production facilities. One of many methods to do effectiveness evaluation is by using Overall Equipment Effectiveness method, with the measured OEE for ST Block 1.1 unit at 81.30%. The measured OEE value is considered below the required standard and six big losses method is used to determine the most significant factor that affects the low effectiveness. Six Big Losses method concludes that the most significant factor that affects the low effectiveness of ST Block 1.1 unit is reduced speed losses, contributing 98.38%. FMEA method also identifies failure modes in ST Block 1.1 unit with the highest risk failure mode being HRSG with RPN score of 108. FMEA method is then followed by RCM method to determine the most suitable action to mitigate each of the failure modes.
